-----------------------------
Summary: Issue with column alias
Key: DRILL-5467
URL: https://issues.apache.org/jira/browse/DRILL-5467
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.10.0
Reporter: Rakesh
The column alias is not always correctly used in output. When columns as
calculated in nested table, the outer most project doesn't show the column
alias correctly:
SELECT `Custom_SQL_Query`.`Bucket` AS `Bucket`,
SUM(`Custom_SQL_Query`.`male`) AS `sum_male`
FROM (SELECT first_name as `Bucket`, salary as `num`, case when gender = 'M'
then 1 else 0 end as male, case when gender = 'F' then 1 else 0 end as female
FROM cp.`employee.json`) `Custom_SQL_Query`
GROUP BY `Custom_SQL_Query`.`Bucket`
Here 'sum_male' appears as $f1 instead
